A few days ago Sony released the 11th version of their consumer "Movie Studio HD Platinum" version of their popular PC video editing platform, Vegas. A variety of new features can be found in it, most importantly 3D stereoscopic editing support, and a faster h.264 decoder for AVCHD/digicam/dSLR footage.

Vegas does not have AVCHD smart-rendering. It only supports this for some AVI formats, DV and HDV.

Regarding webm/ogv, Vegas only supports Video for Windows and Quicktime, not the newer protocols, so only third party codecs that decode/encode in AVI or MOV are supported. Everything else must be written by Sony.
